gdtools: Font Metrics and Font Management Utilities for R Graphics
Compute text metrics (width, ascent, descent) using 'Cairo'
and 'FreeType', independently of the active graphic device. Font
lookup is delegated to 'systemfonts'. Additional utilities let users
register 'Google Fonts' or bundled 'Liberation' fonts, check font
availability, and assemble 'htmlDependency' objects so that fonts are
correctly embedded in 'Shiny' applications, 'R Markdown' documents,
and 'htmlwidgets' outputs such as 'ggiraph'.
